  2. 16. Interactions between plants, microbes and insects

    Author : Laura J. A. van Dijk; Ayco J. M. Tack; Arjen Biere; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; aboveground–belowground interactions; Anemone nemorosa; fungal pathogens; insect herbivores; plant–pathogen–insect interactions; pollination; soil microorganisms; spatiotemporal disease dynamics; Quercus robur; ekologi och evolution; Ecology and Evolution;

    Abstract : Plants interact with an astonishing diversity of insects and microorganisms. Both above- and belowground, plants are attacked by herbivores and pathogens, and interact with mutualists such as pollinating insects and beneficial microorganisms. READ MORE

  4. 17. Interactions between ungulates and forest insects

    Author : Michelle Nordkvist; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : In forest ecosystems ungulates and insect herbivores often co-occur and utilise the same host trees. Herbivores that share a host plant can indirectly affect each other through plant induced responses. Such changes may affect plant growth, interactions with other species, and population dynamics.

  5. 18. Food selection and fitness optimisation in insects

    Author : Helene Bracht Jörgensen; Biologiska institutionen; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; food preference; nested PCR; fungal DNA; växtparasitologi; plant parasitology; Entomology; Entomologi; fungi; seeds; ground beetles; collembolans;

    Abstract : To optimise fitness is a continuous process which assists species survival in changing environments. Choosing an optimal diet is an essential part of the optimisation process and a key element of optimal foraging theory. READ MORE

  6. 19. Pollination and fungal disease transmission : interactions between Viscaria vulgaris, Ustilago and insects

    Author : Ola Jennersten; Uppsala universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP;

    Abstract : .... READ MORE

  7. 20. Olfactory cues and insects - scaling relations and immigration rates

    Author : Petter Andersson; Stockholms universitet; []
    Keywords : växtekologi; Plant Ecology;

    Abstract : For herbivorous insects, location of host plants and habitat patches strongly depend on the type of sensory cue that is used during the search process and the probability of detecting a patch depends on the relative attraction between patches of different size. The visual impression of a patch increases predictably with the patch diameter and consequently, immigration rates of visually searching insects are often predicted by the scaling to patch size of visual cues.
